SynoPiia / PSXS5

PlayStation 1 emulation, running natively on a jailbroken PS5.

## What is PSXS5?
PSXS5 (PlayStation X Super 5) is a PlayStation 1 emulator that installs as an app on the PS5 home screen.
- Two emulators are built into the app:
 - Beetle PSX HW (Mednafen), accurate, and drawn on the PS5's GPU through Vulkan at up to 16x the PS1's resolution, with PGXP.
 - PCSX-ReARMed, on the CPU. It needs no BIOS.
 - PSXS5 picks Beetle when it can, game by game.
- You pick a game from a cover-flow shelf with your covers.
- RetroAchievements, cheats for every game, save states and quick resume.

## A passion project
PSXS5 is a hobby project, made for the love of the PS1 library. No company or schedule is behind it, and nothing is for sale. Expect rough edges. Bug reports that come with `/data/PSXS5/logs/psxs5.log` are the most helpful.
## Highlights
- **Up to 16x resolution on the GPU.** Beetle PSX HW renders through Vulkan: native, 2x, 4x, 8x or 16x, at full speed.
- **No more wobbly 3D.** PGXP (precise geometry) keeps polygons still and textures straight.
- **The right emulator, automatically.** *Emulator: Automatic* uses Beetle when the BIOS for the game's region is there, and PCSX-ReARMed otherwise. Both share one memory card per game.
- **Five themes.** Classic, Neon Arcade, Memory Card (light and dark, a grid of covers) and Record Shelf (spines on a shelf), each with its own colours and fonts.
- **The DualSense as a light gun.** Point the controller at the screen in GunCon and Justifier games (Time Crisis, Point Blank...); R2 fires.
- **Adaptive triggers.** R2 feels like a gas pedal in racing games, and R2 / L2 can be the gas and brake.
- **Profiles.** Each person keeps their own memory cards, save states, settings, play time and RetroAchievements sign-in.
- **Text guides and manuals.** Read a walkthrough `.txt` or a manual's pages from the in-game menu.
- **Game art.** Title screens and gameplay pictures in Details, the game's own artwork around the picture, and an idle slideshow.
- **Quick resume.** Leave a game and pick it up later: the shelf offers *Continue* (with a picture of where you were) or *Start over*.
- **Rewind and fast forward.** Hold the touchpad and press L2 to go back a few seconds, or R2 to speed through cutscenes.
- **Save states with pictures.** Ten slots per game, each showing a thumbnail and how long ago it was saved.
- **One-switch widescreen.** Turns on a game's widescreen code from the cheat library and shows 16:9.
- **CRT look.** Light or strong scanlines, and a soft glow or a 90s TV around the picture.
- **Up to 4 players.** A multitap for the games that support it: each PS5 controller is a player.
- **Fan translations.** Put a `.ppf` patch next to a game and PSXS5 applies it when the game starts.
- **Memory card manager.** See the saves on every game's card, export cards for other emulators, import `.mcr`, `.mcd`, `.srm` or `.gme` cards.
